CHECK JACOBIAN

 

Description: This function allows the user to check for element distortion against the element's ideal shape, which is given a Jacobian value of 1.0.  The more an element is warped the closer it approaches a zero Jacobian value.  Elements that fail the Jacobian check are highlighted and the user has the option of putting them in a separate part.

 

Usage:

 

1.      DSI prompts:

 >     ENTER THE CRITERION FOR JACOBIAN CHECK (DEFAULT 0.7)

 

2.      DSI prompts:

 >     XXXX ELEMENTS FAILED CHECK

 >     INCLUDE FAILED ELEMENTS IN A NEW PART? (Y/N)

 

3.      If YES, DSI prompts the user to define a new part.

 

4.      If NO, DSI prompts the user to check individual elements for Jacobian value via cursor pick.  Select EXIT to exit the function.
